Warning: the new guy asked if the pitot tube was "supposed to breathe like that"
Last Thursday at our hangar in Mesa, a fresh hire was doing a walkaround and leaned into the nose asking me if the pitot tube on the left wing was "supposed to breathe like that." I walked over expecting a loose static line and found a mud dauber nest packed about two inches deep in the probe. He thought the little puffs of air were some kind of airflow test and had been standing there watching it for a bit. We pulled the whole thing, tagged it, and found two more tubes on that ship with partial blockages, so now our crew does a cap-and-tape check before anything else moves. How are you all handling critter plugs when a plane sits outside for a month, is covers enough or are you pulling probes anyway?
